AU'roMoBiLn-BUFFER. 4A'r'rAcHna.

of Philadelphia, countyof Philadelpl'iia,v

State of Pennsylvania, have made ,a 'certain new and useful Invention Relatin to ,Autoi mobile-Buffer Atta'chers,l of whic ,the following is a specification, taken in connection with the accompanying drawing.

Thisjnvention relates to angle bolt or 'alinin'g buffer attachers by which automobile buffersor bumpers or other .littings kor attachments V- having supporting? members' may be secured or clampedto the apertured frame members of automobiles or other ve# hicles.` When, vtor instance, the channel frame members of an automobileare fori-ned with several round orother frame apertures Serial at substantially' a standard distance apart angle .bolt attachers having any suitable bent over or holding ends or contact portions maybe inserted. into these apertures from the outside ot' the frame member and then tipped up orturned to bring their, bent over` or holding ends into laterally projecting osition in which they may be retained by t el alinin'g'acton of the bolt -stems which may pass through suitable slots-or `apertures in the supporting members of-'the automo'- bile bufer or other attachment. The invention inthis application which is a continuation in art of my' cot-pending' application, o. 276,899, tiled February 14, 1919.', relates especially to attachersvotl t is general chafactr-in which the attacher vstems are forined" with rotary alining-,ribs or projections of any suitable form extending from the .attacher stem or shank in a plane substantially perpendicular vorl at least transe attacher.

verse to the lane of the holdingend of the advantageous when attachers ot' this type are used inL connection with buffer supporting bars or members l i rotary alining proosition the attacher jections automatically extends in a plane so that its holding en y substantially perpendicular or at least transverse to the buffer slot, the sides of which may have ai desirable non-'tipping alining action on the attacher stein and maintain-'its bent end in holding position especially 4if thc attacher'stem corresponds approximately to thewidth of thebuer slot. These rotary alining projections' or portions may also advantageously act as retainers and regulate Specication of Letters Patent.

The automobile or other vehicle buffer or bumper may be of any desired form and construction and may have a resilient or other front portion S to which is secured as by theinterposed loo the .resilient or other supporting member which mayin some cases have an offset portion 20 so that these supporting members are carried around 'any' 6 or other' projections on the auto mobile trame. 'The frame members of the automobile may be of an desired channel iron or angle iron type-o construction andvv as indicated-.in Figs. 1 and 2 the frame may comprise the web 1 and the integral frame fiangesQ, 3 to which the usual mudguards and splash pan 5 may be riveted or otherwise secured, and the rivets 6 may secure to i the end of each of these frame members or goose necks the connection for the spring 4: or other part of the. automobile. These frame ends may be conveniently formed with circular or other frame apertures, inch as 12, which may be punched or otherwise' formed 'in the' frame members and located at 'suitable distances from their ends and preferably at aI apart so that the attachment olf-automobile buers and other -iittngs may be facilitated.

substantially uniform distance;

The spacing of these trame apertures pret`- erably corresponds with 'the distance between the adj Listing slotsv` holes or other apertures which are formed in the supporting members ot automobile boilers olf Various types and as shown in Fig. l. the supportinp;l member 7 of the butler may 'formed with adjusting slots l0, ll, although one or more olf these slots may Fbe given an obliquely inclined position as in the case oi the butler slot 30 in Fig. 3.

The stems 1.5 of these angle bolt attachers are preferably of such size as to at least approximately correspond to the width of the adj usting' slots or apertures in the automobile butler or other attachment to be secured to the 'vehicle and many forms ot rotary alining projections may be formed or provided on the attacher stems preferably eX- tending' theretrom in a plane substantially perpendicular to or at least transverse to the plane oi the bent end or holding' portion of the attacher so that these rotary alining projections automatically position the holding end transvt-rsely ol the plane ol" the briller adjusting slot. Figs. l. to 7 show rotary alining' projections 2l which may be in the 'form ot several pinched up or projecting portions 2l which as indicated in Fig. 7 may together constitute a rotary alining projecn tion or member extending' transversely from the stem 15 with respect to the holding end 13 so as to cooperate with the butler slot. l1 and insure the substantially transverse or perpendicular positioning' of the holding end with respect to this slot. ln this way as seen in Fig. 5, 'the attache i' stem 15 which may approximately correspond to the Width of the butler slot ll is alined with respect thereto so that lwhen in tight securing position the attacher cannot tip up in such direction as to release the holding end ll Atrom engagement with the vehicle trame member L The thickness of the usual butler suppoitingg members or bars 7 is considerably greater in that the fame web l used in that the buffer adjusting' slots may thus exert a desirable non-tipping alining action on the attachers especially since the attacher stems may fit considerably more' closely within these slot-s than within the traine apertures in which 'the holding ends .i3 the attachers and their bent portions le must be tipped or turned to brine' the attachers into holding` position. These non-rotary alining projections may also be adran'a' geously positioned on the attacher that they act as retainers in jn'eventnng undesirable or excessive insertion of the at tacher into the vehicle vtrame member. and as shown in `Fics. ah i and il 'th 'e alini t projections 2l may be formed of' arranged on the attacher stein so as to engage outer surface ot the 'traine member l and thus quize definitelyl lost automobiles so` the projecting stems of the attachers without any `great diliiculty. This work can thus be done not only by the ordinary garage man but also by the automobile owner himseltwhich is quite desirable in many cases.

The alininn' stems l5 ot' these attachers or angle bolts may be formed with any desii-ed typo ol fastening device, such as the threaded portions l? and in addition to the aliningv action secured between these at! tachcr stems and the bull'er adjusting slots or other apertures additional non-tipping' alining' action may be secured by the co operating' fastening' means, such as the washers or nuts l) which may also with advantage lit tightly 'enough and have their inner tacos trued up sudiciently to exert considerable alining action in connection -with cooperating parts or 'faces against which they arc secured when the nuts are tiu'l'itened on the alining stems of the angle bolts or attachers. This tightening action brings the holding' or contact portion ot the angle bolt into tight holding engagement with the inner side of the 'frame web or member preferably closely adjacent the frame aperture, for which reason the bolding' end lil of the attacher is made relatively short indicatori, the tip 1G oi this holding; end extending from the attacher .stein in sonic cases no more than about the diameter of the stem. This strengthens the holdinp; end against bending strains and also has the advantage of preventing' its linde-- sirable contact with the traine flanges so as to interfere with the desired positioning et the attacher. Oi" course where in special cases the trame apertures are formed adjacent one o'l the trame flanges the attacher maybe erted and alincd in connection with the cooperating' parts so that its holding end projects away `from and not toward the. adjacent iframe flange, there being' oi' course two allowable positions of the attacher cnil either one ol which may be attacher is inserte l.

8 shows another vtorna olf rotary alining' projection which may as indicated consist ol' a single pinched up portion or projecticai pin l up or otherwise formed from the material ot the attacher stem 15 and. projecting 'therc'lr in in a transverse chosen when the direction with respect to the holding end 13 of the attacher. This alining projection thus insures the substantial or approximately transverse positioning of the hold- .s

versely positioned With respect to the buiier' adjusting slot with which this attacher stem engages. Such rotary alining projections may be formed on the stem of the angle bolt or attacher in any suitable way, as for instance, by drop forging methods which may be used to give theholding end or other.

25 parts of the attacher any desired special shape. Fig. 10 shows anothervform of rotary alining projection which may be similarly formed on the attacher stem so as .to project transversely to the holding end 13 of the attacher and thus position this holding end 'with respect to the buffer adjusting slot through which the attacher stem and its integral alining projection may extend. A single fullwidth or inte-- Blijf-(gral alining projection of this character -is in somerespects preferable to the double alining projection shown in Fig. 9 since When the attacherl stem hasy only a single projection itmay fit somewhat closer to the 40 end of an adjusting slot so as to give full range oftadjustment to the cooperating buffer or other vehicle attachment.
